INA170EA/250G4 datasheet by Texas Instruments

INA170EA/250G4 Frequently Asked Questions (FAQs)

• What is the maximum voltage that can be applied to the input pins?
  The maximum voltage that can be applied to the input pins is 40V, but it's recommended to keep it below 36V to ensure accurate measurements.
• How do I calculate the gain of the INA170?
  The gain of the INA170 is fixed at 8V/V. This means that for every 1V of input voltage, the output voltage will be 8V.
• What is the purpose of the REF pin?
  The REF pin is used to set the reference voltage for the output. It's typically connected to a stable voltage source, such as a voltage regulator or a battery. The output voltage will be referenced to this pin.
• Can I use the INA170 to measure AC voltages?
  The INA170 is designed to measure DC voltages. While it can measure AC voltages, it's not recommended as it may not provide accurate results. If you need to measure AC voltages, consider using a dedicated AC voltage sensor or a different amplifier configuration.
• What is the input impedance of the INA170?
  The input impedance of the INA170 is typically around 1MΩ. This means that it can be used with high-impedance sources, but may not be suitable for low-impedance sources.
